The cumene process (cumenephenol process Hock process) is an industrial process for synthesizing phenol and acetone from benzene and term stems from cumene (isopropyl benzene) the intermediate material during the process. It was invented by R. Ūdris and P. Sergeyev in 1942 (USSR). and independently by Heinrich Hock in 1944 This process converts two relatively cheap starting

Synthetic phenol capacity in the United States was reported to be ca x 10 t/yr in 1989 (206) almost completely based on the cumene process (see Cumene Phenol). Some synthetic phenol 108952 is made from toluene by a process developed by The Dow Chemical Company (2 299—301).
Phenol and acetone production consumes approximately 98 of all cumene globally therefore cumene demand is closely tied to the phenol and acetone markets. The following pie chart shows world consumption of cumene In 2022 global cumene consumption will be just under 17 million metric tons with most of the market activity occurring in the

This cumene process involves contacting in an alkylation zone a first benzene recycle stream and a propylene feed stream with an alkylation catalyst to form cumene. In a transalkylation zone a polyisopropyl benzene recycle stream and a second benzene recycle stream are contacted with a transalkylation catalyst to form additional cumene.
Cumene production follows the demand for phenol and its derivatives. In 1987 the cumene demand estimated at million metric tons was supphed by about million metric tons of domestic production imports made up the balance. Based on a trend from 1985 on the demand is projected to increase at about 3 per year through 1995.

The degradation of the cumene hydroperoxide proceeds via a carbocation mechanism. In the first step a pair of electrons on the oxygen. of the hydroperoxide s hydroxyl group is attracted to a proton of the H3O molecule forming an oxonium ion. The oxonium ion becomes stabilized when the positively charged oxygen leaves in a water molecule.
